1. Risk Profile
- Overall Risk: Low Risk (Risk Score: 15)
- Ownership: Assigned to OVH (ASN 16276), registered to Dmytro, Ahrefs Pte Ltd.
- Geolocation: Country CA (Canada), but city field indicates Singapore (potential discrepancy). Coordinates and timezone remain unconfirmed.
- Network Role: CloudCompute infrastructure (OVH-hosted), no residential/mobile/mobile carrier association.
2. Threat Indicators
- No malicious indicators detected (no spam, known attackers, or DNSBL listings).
- No active services or TLS certificates observed.
- No correlated campaigns or threat feeds linked.
3. Observation History
- Recent Activity:
- Identified as a CloudCompute instance (OVH) with stable routing (BGP route stability confirmed).
- Geolocation data showed inconsistent city (Singapore) vs. country (Canada).
- Subnet abuse density (148.113.128.0/24) is moderate (0.344), with 86 of 250 sibling IPs flagged as threats.
- No persistent malicious behavior or ownership changes detected.
4. Relationships
- Network Associations:
- Linked to OVH-CUST-281059693 (same network).
- DNS association with proxy-ca014-san137.ahrefs.net (hostname resolved to this IP).
- Certificates/Services: No TLS certificates or open ports detected.
5. Subnet Neighbors
- Subnet: 148.113.128.0/24
- Abuse Density: 34.4% (moderate).
- Neighbor Risks:
- 81 low-risk IPs, 19 medium-risk IPs, 0 high-risk IPs.
- Notable: 100% of neighbors are OVH-assigned, with no external malicious entities.

6. Actionable Insights
- Monitor Subnet: The 148.113.128.0/24 subnet has a moderate abuse density. Investigate suspicious activity in neighboring IPs (e.g., 148.113.128.0, 148.113.128.1).
- Verify Geolocation: Discrepancy between country (Canada) and city (Singapore) warrants further validation.
- DNS Association: The hostname proxy-ca014-san137.ahrefs.net is tied to this IP. Confirm if this is a legitimate Ahrefs service or potential phishing vector.
- No Immediate Threat: No direct malicious indicators, but the subnetβs moderate risk profile suggests heightened monitoring for lateral movement or compromised hosts.
